As long as a man can keep himself in that attitude of mind,
as long as he can look back on every year
and say, "I grew", he is still young.
The minute he ceases to grow, the minute he says to himself,
"I know all that I need to know,"——that day youth stops.
He may be twenty—five or seventy-five, it makes no difference.
On that day he begins to be old.
一个人,只要他能够保持这种心态,
只要他在回首过去的一年是能够说“我在成长”,他就依然年轻。
他一旦停止成长,他一旦对自己说“我该懂的都懂了,”
这个时候他的青春也就完了。
他可能在25岁时死去,也可能在75岁时死去,这都没有区别。
就在那一天,他开始变老。
